In the drawings which show a preferred embodiment of my invention, thenumeral 1 designates the cowl of an automobile, 2 the hood, 3 the dash,4 the toe board,

The "only operating part above the housing is the roller 12 mounted toturn-on'a stud 13 which moves-in a slot 1'? provided in the housing.Sleeve 1-8 is threaded and screws onto stud-13 provide. a which the suchnovel theroller from-sliding down on the'studiand rubbing onthehousing." .The roller is provided witha bushing :10 and is held on thestud 13 by" its head.= :A vflange llis provided on the base of therollerand is adapted to'be engaged by the sole of the operators shoe andwill thereby prevent the upper part of the shoe from touching the rolleror from becoming soiled thereby. The lower part of the stud is threadedand is screwed into a threaded holeinthe end of the lever 16 and a nut15 serves as a lock nut' to prevent it from loosening.

The lever 16 is secured to a sector 19 by means of a screw 20 and aslotted end at 21 which fits partly over a bolt 22. The sector 19 whichis shown in Figs. 2 and 3 is provided with teeth shown at 29 which meshion 28. This pinion is rigidly secured to the end of a shaft 30. A guide43 is provided to hold the sector in mesh with the pinion.

A bracket 24 is secured within the housing by means of screws 26 and 27and serves as a frame to hold the sector 19 and the pinion 28. It isprovided with a journal 25 in which the shaft 30 finds its bearing. Thesector turns on the bolt 22 which passes down through the bracket and isheld by a nut 23. The other end of the shaft 30 finds its bearing in theforwardend of the housing 7.

A depression arm 31 is secured to the shaft 30 by means of a clamp screw32 and is adapted to engage a plate 34attached to the end of the rod 39which leads to the throttle valve of the carburetor. The depression armis provided with a hook 33 formed on its end to engage the plates 34 or35.

Some cars are provided with a throttle valve lever 38 in place of abutton on the end of a throttle valve rod 39 and to adapt my device tothis type of foot accelerator I have provided a plate 35 to be attachedto the lever by means of a bolt 37 and clips 36 adapted to be bent overthe lever.

The operation of the device is as follows:

When it is desired to accelerate the speed of the motor the operatorcauses the sole of his shoe to engage the flange of the roller 12causing it to move across the top of the housing above sole of the theroller in section,

frame and depression designates and 5 the shown) through a '7 securedthus .forminga shoulder at 14 which prevents.

the slot 17 and since the roller is secured to the end of the lever 16and lever 16 is secured to the sector 19 the upper end of lever 16 ismoved to the right thereby turning the sector on bolt 22. The teeth ofthe sector being in mesh with the teeth of the pinion 28 rigidly securedto shaft 30 the shaft is caused to turn and in doing so the depressionarm 31 engages the depression plate 34 or 35 as the case may be,depending on the type of car operated, and since the plate is secured tothe usual accelerator rod 39 it is pushed forward and downward in theaccustomed manner to accelerate the speed of the motor. When the foot ofthe operator is moved away from the roller the usual spring (not shown)returns the accelerator rod to its normal position which in turn movesthe operating parts of my device to their normal position. I

It is to be understood that the form of my invention, herewith shown anddescribed is a preferred example of the same, and that various changesmay be made in the shape, size and arrangement of parts withoutdeparting from the spirit of my invention or the scope of theaccompanying claims.

It will now be seen that I have provided an accelerator for automobiles.and the like which will not be tiresome to the operator because hisfoot rests firmly upon an immovable housing and that the speed of themotor will remain constant while traveling over rough and bumpy roadsbecause the movement of the foot in operating the device is lateralinstead of up and down.

What I claim is:-

1. A foot accelerator including a housing, a slot provided therein, afoot lever fulcrumly mounted in said housing, a stud secured to one endof said foot lever and adapted to travel in said slot, a roller mountedon the upper end of said stud and adapted to turn thereon, a sectorprovided with teeth and to which said foot lever is secured, a shaft anda pinion rigidly secured thereto and adapted tomesh with the teeth ofthe sector, an arm rigidly mounted on said shaft a plate mounted on theconventional foot accelerator pedal or parts leading to the throttlevalve of the carburetor and adapted to be engaged and moved forward bysaid arm.

2. A foot accelerator including a housing, a slot provided therein, afoot lever fulcrumly mounted in said housing, a stud secured to one endof said foot lever and adapted to travel in said slot, a roller providedwith a flange extending around its base and mounted on the upper end'ofsaid stud and adapted to turn thereon, a sector provided with teeth andto whichsaid foot lever is secured, a shaft and a pinion rigidly securedthereto and adapted to mesh with the teeth of the sector, an arm rigidlymounted on said shaft, a plate mounted on the conventional footaccelerator pedal or parts leading to the throttle valve of thecarburetor and adapted to be'engaged and moved forward by said arm.
